One trick to keep the focus where you want, have the subject stand with the back of their head against a wall to keep them stationary, and use a tripod so your camera doesn't move either.
get plenty of indirect light TO the eyes, whether by reflector, window, standing very close to a light source - whatever it takes. The biggest problem I've found is with shadows under the eyes being unflattering.
Eye drops (Visine, etc.) are your friend. To avoid excess shine on the skin around the eyes, have the person wash their face / skin / eyelids with a mild soap & rinse with cool water. Avoid warm water, as it will bring blood to the area & look red / puffy. Ditto on the tripod.
Awesome, thanks all! But what exactly is a reflector....?
Anything that reflects light gently back onto the subject. If your lightsource is toward one side, naturally the other side will be darker. A reflector on that other side to bounce some of the light onto the dark... well, you get the idea, I'm sure :)
Depending on the situation and the size reflector you need, it can be as simple as a piece of white paper.

A car wind shield reflector works well on a budget. Cheap and it folds up.
